Concrete.... What did I do wrong?

Peachcreek,

The Ucart plant is about 10 minutes from my place, and there was about a 2" layer of water on top of the concrete when it got to the house. Mandi did the hauling, and they told her that they put extra water on top to help with the heat and to keep it from drying out in transport.... Does this sound kosher?

FYI, I am not looking to give the Ucart guy a hard time, and I probably won't bother contacting him, I just want to know what's up for future reference. I do have a handful of projects coming up, and I may just go ahead and form out everything I need for all the projects, and have a truck come pour all of it. Rather than doing each job individually. But if for some reason, I can't do them all at once, I'd like to know how to plan accordingly...
